I hasten to add here that “Heap” here is not the traditional computer science heap, or even the application memory heap, but B.R.

Way back when I’d have written them out in the Equation Editor in Word, and taken screenshots, but this time I decided to go for a browser-based solution: MathJax. In essence, I’d write the expressions in LaTeX format, such as x = \frac {-b \pm \sqrt{b^2 - 4ac}} {2a}, and have it rendered as: […]
